The majority of the programs and applications works, but there are some, which has two versions and they will need to upgrade. However, the majority of the 32-bit programs are running enough well and not needed specially to upgrade, but You can do it.Only, if you do not feel any lack of 64-bit system, you do not need to change. You do not win anything!Moreover yet - all 64-bit web browsers works till today visibly slower than the 32-bit versions.Personally I'm using 64-bit system after the Windows 8.1 arrival.

I used 32 bit until I switched from windows xp. But with windows 7 and 8 and now testing windows 10, they are all 64 but. For the most part, I have not had any problems running 32 bit on 64 bit systems.
